    Legend:
    [+] This domain is secure. The domain's SSL/TLS certificate from Let's Encrypt has been issued/renewed.
    [-] This domain is not secure. Either the domain's SSL/TLS certificate from Let's Encrypt could not be issued/renewed or the domain name was excluded from the certificate. Renew the certificate manually or request a new one to secure this domain.

  • The domain has two certificates.

    • One in the main subscription: Subscriptions > example.com > SSL/TLS Certificates > Advanced Settings
    • Another in Subscriptions > example.com > example.org > SSL/TLS Certificates.

Cause

The notification is for a certificate in the base subscription that is not being used.

Resolution

  1. Log into Plesk

  2. Go to Subscription > example.com > SSL/TLS Certificates > Advanced Settings

  3. Select the unused certificate. Certificates which are in use have a number greater than 0 in the Used column.

  4. Click the Remove button
